Great Northern Insulation

Great service and very happy with the results, we already are seeing the advantage of having it done.

I used GNI for both attic insulation and basement spray foam insulation. After an issue with wildlife in the attic (rescheduled at no cost to me) both the attic and basement jobs went well. Very easy to deal with, price was right and communication was great.

We used them for topping up insulation for 2 homes. In both instances, they were professional from the estimate meeting to the actual work. We will use them again without hesitation.

Experienced sales staff and friendly work crew. Job was completed quickly, thoroughly cleaned up and looks great!

I had GNI come and add insulation to my attic. They did a great job from the initial consultation to the final installation. Would highly recommend them.
